To all whom it may concern.

Be it known that I, Frnn M. STILES, a. citizen of the United States,residing at Cooperstown, in the county of Otsego and State of New York,have invented a new and useful Chimney, of which the following is aspecification.

It is the object of the, present invention to provide an improvedconstruction of chimney and the invention aims primarily to provide achimney which will be fire proof and will embody ventilating means forthe purpose of admitting cooling air into the space between the innerand outer sections of which the chimney is composed.

A 't'urther object of the invention is to provide a chimney of the classmentioned embodying. wedges which are disposed between the corners ofcorresponding inner and outer sections for the purpose of holding thesesections inv proper spaced relation.

It is a further object of the invention to provide, in a-ehimney made upof a plurality of sections including an inner base or bottom section andan outer base or bot tom section, means for so spacing the bottoms ofthe two said sections as to not inter- .fere with the circulation ofcooling air currents therearound.

lVith the above and other objects in view, the invention consists in thegeneral construction and arrangement of parts shown in the accompanyingdrawings, in which,

Figure 1 is a perspective view partly in section of a chimneyconstructed in accordance with the present invention. Fig. 2 is asimilar View in detail of one' corner or" two related sections of thechimney. Fig. 3 is a vertical sectional view through the upper endportion of one side of the chimney wall. Fig. 4 is a. detail perspectiveview of the means provided for s acing the bottoms of the base sectionsof tie chimney. Fig. 5 is a perspective View of one of the wedge shapedblocks.

As heretofore stated, the chimney embodying the present invention ismade up of a plurality of superposed inner and outer sections and theinner course of sections includes a bottom section of specificconstruc-' tion as does also the bottonrcourse, and the chimney furtherincludes, in its structure,

tom section of the inner course is indicated 1 the numeral 5 and abottom wall indicated,

by the numeral 6, this section being open at its top. In a likenianner,the bottom section B of the outer course'of sections, embodies fourvertical Walls 7 and a bottom wall 8. The section B is considerablylargerthan the section A and in building the chimney the section A isdisposed within the section B angl as a means for spacing'the' bottomWall 6. of the section A from the bottom wall 8 of the section B, thereis provided a spaningmember comprising four radialarzns 9 which arerelatively narrow and are of they desired height and have theirends'beveled as at 10 so as to fitsnugly in the corners be-' tween thevertical walls 7' of the section B, it being observed that the section Ais dis posed directly upon this spacing member. For the purpose ofproviding for the.connection of a stove pipe with the chimney, a stovepipe thimble indicated by the numeral 11. is fitted through one or morevertical walls 7 of the section B and opens also through thecorresponding wall of the section A and consequently into the interiorof the section A. The vertical wall of the section B has its upper edgerabbeted as indi;- cated by the numeral 12 and its outer edge beveled asat 13 whereby to shed water. In a like manner, the. upper edge of eachvertical wall section A. is rabbeted as at i l and also its inner upperedge is beveled.

In addition to the bottom section above described, the chimney includes,in its structure, a plurality of intermediate sections and .of theselatter sections, those comprising the inner course are indicated by thenumeral, 15 and those comprising the outer eour'se'are indicated by thenumeral 16. Each section 15, of which there may beanynumber, as-

will be readily understood, embodies four vertical walls and is open atits top and its bottom and the lower edge of each wall of each section15 is rabbeted as at 17 as is also the upper edge of each Wall as at 18.The lowermost one of the sections 15 is disposed ei ia M211 at its lowerend upon the upper end of the section it with the m hheiecl edges 17 ofits vertical "Well fitting the rahhoteri upper edge:-

From en inspection of Fig. 1 of the draw- 5 ing's it will he observedthat the sections and 16 are of the same height so that when thesections are properly arrangel, the lower and upper edges of:corremtmrling sections fiviillhe locatee. in the same horizontal plane.

, on. as well as the heso section A each upper corner with c 1)indicated by the numeral properly space the sections oi' the ter coursesthere are i revii spacing wedges indicated by the nnniierel he, one endof each. of the we figes being 2 e 1 as at 23 L in V-forrn, so as to fitin the cor} er hetvxee i adjacent vertical walls of the enter sectionwhich is to be spaced from the cor- 0 responding inner section, anti.the inn end oi each Wedge 22 is formed with e notcn which is alsoV-siiaped and is cleeper at bottom than at the top, the Wedge heintposed in the position shown in oi.
